摘要： Release mechanism for medical device includes a bushing having a proximal end, a distal end and a channel extending therethrough. Plurality of extend proximally from the distal end are biased toward a release configuration in which engagement surfaces at distal ends thereof retract radially into the channel. A core pin insertable through the channel applies a radially expansive pressure to move the arms radially outward to a locking configuration. Engagement surfaces of the first and second arms connect to a retaining surface of a tissue treatment device containing capsule, which extends at an angle relative to the engagement surfaces selected so that a first portion of a force transmitted along an axis of the bushing moves the arms radially inward toward the release configuration before a second portion of the force exceeds a threshold level associated with the removal of a tissue treatment device from gripped tissue.

摘要： A device 10 for repairing mitral valve leaflets 2, 3 includes a jaw mechanism 15 that may be positioned adjacent a mitral valve leaflet 2, 3. The jaw mechanism 15 may move between an open position and a closed position by pivoting a first jaw relative 16 to a second jaw 18. The first jaw 16 may include a rivet 28 that may move from a stored position to an application position projecting away from the first jaw 16 when the jaw mechanism 15 is moved from the closed to the open position. Closing the jaws 16, 18 about a valve leaflet 2, 3 causes the rivet 28 to pierce the leaflet. The jaw mechanism 15 may then be rotated to wind the leaflet 2, 3 thereabout and again pierce the leaflet. The rivet 28 may then be released from the jaw mechanism 25 and the device 10 removed from the patient.

摘要： A device includes a clip including first and second arms distal ends of which are biased apart and a core member including first and second portions connected to one another via a frangible link. The first portion includes a first protrusion for engaging a cut-out in the first arm. The frangible link is fractured when subjected to a load of at least a predetermined level deploying the clip. The device also includes a capsule slidably housing the core member and a proximal portion of the clip.

摘要： A tissue clipping apparatus comprises a clip including a proximal end received within a capsule. The clip includes a clip locking member biased to engage a first locking structure of the capsule to lock the clip in the capsule in a closed configuration. The apparatus also comprises a tension member releasably coupling the clip to a proximal end of the device which, during use, remains accessible to a user. The tension member is coupled to the clip by a joint designed to release when subject to a predetermined load to separate the clip from the device, release of the joint releasing the locking member to engage the first locking structure.

摘要： A transcatheter method of gathering tissue of a heart valve leaflet may include inserting an elongated catheter assembly to a position adjacent the heart valve leaflet, the catheter assembly including a capture tool moveable between a retracted position and an extended position, a tissue support, and a clamping member moveable between an open position and a closed position. The capture tool may be partially retracted to gather tissue of the heart valve leaflet between the tissue support and the clamping member. The clamping member may then be moved from the open position toward the closed position so as to clamp a substantial portion of the gathered tissue of the heart valve leaflet between the tissue support and the clamping member. Subsequently, a clip may be applied from the catheter assembly to the clamped tissue so as to hold the clamped tissue substantially in a gathered configuration.
